Supports reversal of contractile impairment with mitral valve surgery in chronic MR; hypothesis-generating and requires prospective validation before practice change.
Does mitral valve surgery improve left ventricular contractile function in patients with long-term mitral regurgitation?
Mitral valve surgery reverses left ventricular contractile impairment in patients with long-term mitral regurgitation, particularly in those with preserved preoperative ejection fraction and less dilation.
Mark R. Starling (1995) studied this question.
